1/ Start off by piping some 'brain cream' squiggly lines in the bottom 3rd of the jar. Drizzle some edible blood (about 2 teaspoon) down the sides of the jar. Add a red velvet cupcake on top and pipe some more 'brain cream' on top and finish off with a drizzle of more edible blood.

To prepare brain cupcakes:

1/ Begin by piping a blob of frosting in the centre of the cupcake leaving about 1 centimeter of blank cupcake around the sides. Pipe a line of frosting across the top middle of the blob. Then pipe some squiggly lines around each side of the brain and finish off with a drizzle of edible blood on top.
